New Array with fixed length does not initialize the length

[GoogleCodeExporter]

c#:
        public static T[] toArray<T>(this HashSet<T> self) {
            var ar = new T[self.Count];
            return null;
        }

js:
        toArray$1: function(T, self)
        {
            var ar = []; //Should be: var ar = new Array(self.get_Count());
            return null;
        },

Explictly constructed arrays also suffer from this problem e.g.

c#:

var someInts = new int[5];
console.log(someInts.Length);

will produce

var someInts = [];
console.log(someInts.length);

which in turn ends up with awkward to detect bugs.

The explicit array initialization will also help with performance/memory on 
modern JavaScript engines.
